Im not saying you should do anything....BUT dont believe the 5yr/150,000 mile BULLSHIT....Green works as good or better than Dexcool on ANY engine.

/thread

 

I agree.

I have seen no facts that green is better than dex assuming both are changed in a resonable time frame. IMO, 5/150 is not very reasonable.

I think we can all agree that the biggest issue with dexcool is the recommeded change interval.

 

whats funny is that chocotaco cant even replace his water pump himself, he has to have a mechanic do it for him

i on the other hand have done several intake swaps, changed my water pump (it went out after 130k), dropped the k member out of my car, and completely rebuilt my motor. belive who you want.

people like him take second hand information that they hear at the shop as they are having their cars worked on and pass it off as if they have some clue about what they are talking about. after personaly seeing the inside of my 120k and 160k motors and how absolutly spotless they are, i have no problems with using the dexcool that this motor was designed to use.

 

^^^

Internet mechanics FTW!!!

 

while im just staying out of this pointless debate, i will agree with the ChocoTaco passing off information without actually doing it himself remark.

 

Well...I'll let you know if my electric water pump blows up on its maiden voyage in about five minutes

If it does though, I'll only have myself to blame since I installed it along with the evil Dexcool

 

Didn't you know that Dexcool is actually the Devil himself reincarnated in an automotive antifreeze coolant?? What else could explain all this paranormal activity?? Coincidence?? Impossible!!!

 

BAD NEWS:

Just got back from taking the car out for a spin, and the motor is still in one piece...water pump too The only reason I put Dexcool in was to blow up my engine so I could get another one...

 

Dexcool is great for LS1's if you change it often. But with an iron block (LT1) and neglect it males big trouble. I bought my 96 T/A with 96,000 and no one had changed the coolant (or at least for the last 50,000 miles). Because these cars aren't new anymore and god knows what kind of person owned the car before you I say swap it over. I hate Dex becuase of the experience I had with it, but I'm sure if you have had your car since new or close to it you may like it. When I buy my next car I'm going to sawp to the good old green as soon as possible because I'm sure the car will have at least 70,000 on the clock.

 

Why would you swap it over to green just because the previous owner may have left Dexcool in for too long? That doesn't make any sense. Why not just flush the system, then refill with Dex, then change it regularly?

If the coolant has been left in for 70-90k miles, then whatever damage might have been done, has already been done. Swapping over to green stuff isn't like some kind of magic potion that will reverse the effects of years of poor maintanence and fully restore your cooling system.

Flush out the old dex, and put in new. Or, if you prefer, flush the system and refill with green. But don't expect the green to save you from damage that has already been done. If the system was damaged in any way by old coolant, it's not going to make a damn bit of difference whether you refill with dex or green, the damage will need to be repaired either way. And if you were lucky enough to not have any damage from the poor maintanence, then refilling with fresh Dexcool and changing it regularly isn't going to create any new issues.

 

Well said.

 

Damn, it took you so long to reply that I was certain your motor had been sucked into the 7th layer of hell and was burning as I type.

Didn't you know that dexcool is Satan's Lemonade?

 

I didn't know that...my girlfriend said it looked like Kool-Aid. I told her it tasted like it too She declined my offer to take a sip

 

Maybe I should have said, Satan's *pink* Lemonade.

 

EXACTLY my point!

 

LS1s do not have see a problem with intake gaskets because THEY DO NOT HAVE coolant in the INTAKE AREA... I had no problems with Dex in my 99 camaro or Z06 but I got rid of it very early BECAUSE I have PERSONALLY seen what it does to gasket materials on at least 100 other vehicles. The people who have the most experience with Dexcool and its issues advocate getting rid of it. Simple fact even in this thread......

Don't believe me just go to a service bay at your local GM dealer and ask a few mechanics.

Last post here. I promise....

 

Yep,

Have to go based on personal experiance and not just the word of others. For me, I've owned at least a half dozen various types of cars with dexcool, and another half dozen cars with green stuff. Here is what I have learned:

Leave dexcool in too long, you'll have problems.

Leave green stuff in too long, you'll have problems.

Change dex or green regularly, you'll have no problems.

In the end, pick either, change often, live happily ever after. That's what I've learned based on my own personal experiance without the influence of anyone else's opinion, so that's my personal final conclusion.

 

I'm a bit embarrassed to chime in on this topic, but I'd rather get ripped by people who will spout off at the mouth then have another F-body owner have to go through this.

This is my coolant on 60k on my 98Z. I purchased this vehicle with 42k and thus far have had no performance or water pump issues. I'm a newb, but fortunately, I'm learning through this site to start taking care of my ride. However, this is what I found, and I assume the previous owner did little maintanance.

The pic above was AFTER someone had smudged most of it off with their finger. It does in fact smell horrible and was gunkier than crap. So here is someones "proof" if they feel they need it. Chaco has a right to be worried, and I do think those of you that raised an eyebrow with the post should as well.

I do realize the right change interval would help. I will not argue my opinion if it will work if I had changed mine earlier or not. Surely there is sense in that. But how soon? 2yrs would probably be cool, but again, I don't know for sure. I simply will state the facts and let you guys decipher what you feel is best FOR YOU. Please just don't let it get to this point....or worse.

 

What you just showed could have easily been prevented by just checking that overflow tank...mine got that way too once upon a time because I never checked it. Never had that happen since I started keeping the level where it needs to be.

 

oops, another pic, may be clearer.
